Pierre (SD) Water Quality

Pierre is a large public water system in EPA region 8 that provides tap water for the 57501 zip codes. It has 16 facilities where the water supply was tested for 82 chemical contaminants that impact tap water quality and human health.

The maximum reported level of HAA5 (five regulated haloacetic acids) was 5.12 µg/L. The maximum reported level of Manganese was 2600 µg/L. All 2 of the latest water samples showed levels of Manganese that were at or above unsafe concentration levels. There were 2 contamintants found in the Pierre water supply at levels that were above the minimum reporting level. 1 of the contaminants were above the reference level, which means they may pose a risk to human health.
